In  the  enumeration  of  the  drugs  and  preparations,  after  the  present  officinal 
name  that  of  the  first  edition  of  the  Norwegian  Pharmacopoeia  is  given  next, 
then  follows  the  officinal  names,  and  whore  the  preparations  vary  in  strength 
these  variations  are  likewise  indicated,  ef  the  Swedish,  Danish,  Piussian.  Ger- 
man, Austrian,  British,  United  States  and  French  Pharmacopoeias,  and  finally 
the  popular  name  is  given  before  the  formula.  The  blistering  plaster  contains 
6  parts  cautharides  in  22  parts  of  the  plaster;  the  heading  is  as  follows  : 
Emplastrum  cantharidum  ordinarium.

To  each  drug  a  short  concise  description  is  added,  and  attention  drawn  to 
probable  admixtures  or  substitutions,  these  descriptions  being  sufficiently  defi- 
nite for  those  acquainted  with  drugs,  but,  like  in  all  other  pharmacopoeias  with 
a  similar  feature,  are  insufficient  for  the  beginner.  The  following  description 
of  uva  ursi  will  explain  this  : 
Arctostaphylos  uva  ursi,  Sprengel  (Arbutus  uva  ursi,  L.)  Ericineae  fruticulus 
in  Norvegia  frequens. 
Fttlia  obovata,  coriacea,  integerrima.  glabra,  nitida,  reticulato-renosa.  Ne 
confundantur  cum  foliis  Yaccinii  vitis  idaeae,  L  ,  margine  reflexis,  subtus  opacis 
et  fusco  punctatis. 
Folia  aestate  colligenda. 
But  few  formulas  are  given  for  chemical  preparations  ;  except  in  cases  where 
they  are  intended  of  a  certain  condition,  chemicals  are  merely  described,  and 
the  principal  reactions  of  identity  and  purity  appended.  The  nomenclature  is 
substantially  the  same  as  adopted  by  Berzelius.  namely,  acetas  morphicus, 
oxydum  hydrargiricum,  subnitras  bismuthicus,  &c.  The  chemical  formulas, 
according  to  the  old  notation,  follow  the  officinal  name. 
The  formulas  for  the  galenical  preparations  contain  short  accurate  directions 
which  are  not  intended  for  the  mere  tyro  ;  the  processes  are  as  simple  as  the 
nature  of  the  product  to  be  obtained  will  admit.  Displacement  is  not  prac- 
ticed ;  tinctures,  unless  otherwise  directed,  are  made  by  heating  the  suitably 
comminuted  drug  and  the  menstruum  in  a  retort  to  a  slow  boiling  for  half  an 
hour,  so  that  scarcely  any  distillate  is  obtained  ;  after  cooling,  the  distillate  is 
mixed  with  the  contents  of  the  retort,  the  liquid  expressed  and  filtered. 
All  quantities  are  expressed  in  parts  by  weight. 
Taken  as  a  whole,  the  Norwegian  Pharmacopoeia  is  up  to  the  requirements 
of  the  present  time,  although  the  American  pharmacist  would  hardly  be  pleased 
with  all  the  manipulations.  We  append  the  formulas  of  a  few  preparations, 
which  are  not  or  but  little  known  here,  and  retain  the  officinal  names  of  the 
Pharmacopoeia  unaltered :
